Abstract: The present disclosure provides systems and methods for generating an electrophysiological map of a geometric structure. The system includes a computer-based model construction system configured to acquire electrical information at a plurality of diagnostic landmark points, assign a color value, based on the acquired electrical information, to each of the diagnostic landmark points, create a first 3D texture region storing floats for a weighted physiological metric, create a second 3D texture region storing floats for a total weight, for each diagnostic landmark point, additively blend the color value of the diagnostic landmark point into voxels of the first 3D texture region that are within a predetermined distance, normalize the colored voxels using the second 3D texture region to generate a normalized 3D texture map, generate the electrophysiological map from the normalized 3D texture map and a surface of the geometric structure, and display the generated electrophysiological map.

Abstract: The present disclosure provides systems and methods for generating a multi-dimensional surface model of a geometric structure. The system includes a device including at least one sensor configured to collect a set of location data points corresponding to respective locations on or enclosed by a surface of the geometric structure, and a computer-based model construction system coupled to the device. The computer-based model construction system is configured to generate a working volume based on the set of location data points, calculate a dilated field for the working volume, define a dilated surface based on the dilated field, calculate an eroded field for the working volume based on the dilated surface, and define an eroded surface based on the eroded field.
